Ok, I'm a little confused about what you want, but I'll try to answer.
If you have a hash:
my %hash;
$hash{computername}{description}{'failed pings'} = 3;
then saying:
my @keys = keys %hash;
print "@keys";
will print:
computername
In other words, the keys function will not find keys in all references to
get the keys in a hash ref you have to say
my @keys = keys %{ $hash{computername} };
Hope that helps!
